2 Claims. (Cl. 20--55) My invention relates to storm windows, and moreparticuarly relates to storm windows with removable inserts for casementtype windows.

In my invention, the storm window frame is fabricated of wood, metal, orplastic so that it may easily be attached to the inside face of acasement type window casing and the removable glass and screen sasheslie flush within the wood frame and are slidably supported. Means arealso furnished for providing an adjustable deflector type ventilator.

Heretofore, casement windows were provided with outside storm sasheswhich were bulky in appearance and difficult of application and removal.Although the known forms of inside metal frame storm windows solved someof these difficulties, they also have other objectionable features thatlimit their coverage and performance.

It, therefore, is an object of my invention to provide a storm windowframe having removable window glass and screen inserts for casement typewindows which can readily be installed as a unit from the interior ofthe building.

Another object of my invention is to provide a storm window frame forcasement type windows having inserts of single panel glass and whichalso may embody a ventilator opening.

Another object of my invention is to provide a storm window for acasement type window that provides the greatest coverage of both glassand metal of the prime window using the least amount of space inobtaining this object.

Another object of my invention is to provide a compact storm windowwhich does not disfigure or mar the prime casement window.

Other objects of my invention are to provide an improved device of thecharacter described, that is easily and economically produced, which issturdy in construction, and which is highly efiicient in operation.

With the above and related objects in view, my invert-- tion consists inthe details of construction and combination of parts, as will be morefully understood from the following description, when read inconjunction with the accompanying drawings in which:

Fig. 1 is an elevational view of the interior of a casement type windowcasing and a wooden, metal, or plastic storm window frame for theaforementioned casement showing a typical mounting of storm window,screen, and ventilator inserts embodying my invention.

Fig. 2 is a sectional view taken along lines 22 of Fig. 1.

Fig. 3 is a sectional View taken along lines 3-3 of Fig. 1.

Fig. 4 is a sectional view taken along lines 4-4 of Fig. 1.

Fig. 5 is a side elevational view of the easement type storm windowembodying my invention showing the upper storm window insert in positionand the ventilator in an open position.

Fig. 6 is a close-up fragmentary view showing the Patented Nov. 22, 1955manner in which the upper storm window insert is held in position withinthe storm window frame on the frame Clasps.

Fig. 7 is a fragmentary view of the easement window latch mountedadjacent the storm window frame showing the manner of operation from theinterior of a building.

Referring now in greater detail to the drawings, in which similarreference characters refer to similar parts, I show a casement window ofthe conventional type comprising vertically-pivoted, outwardly swingingcasement sash, generally designated as A, mounted within a windowcasing, generally designated as B.

The casement type sash A is vertically pivoted upon hinges 10 so as toswing in a horizontal direction. Each hinge is comprised of a leaf 10Awhich extends in an outward direction from the casement sash A, and acooperating leaf 10B which extends in an outward direction from thecasing B, the leaves 10A and 10B being pivotally connected to oneanother by a pin NC. A manually operated crank 12 located interiorlydrives a worm gear (not shown) for regulating the opening and closing ofthe swinging sash from the inside by means of a connecting pivotallymounted lever arm 14.

interiorly spaced from the sash A when in a closed position and amxed tothe window casing B is a storm sash embodying my invention.

The storm sash comprises a wooden, metal, or plastic frame, generallydesignated as D, which is a permanently affixed frame and has includedtherein removable inserts, each of which is generally designated with aprimary letter E.

The wooden, metal, or plastic frame D is permanently afiixed to thecasing B by means of screws or nails and is finished with woodenmoulding along the edges. The frame D comprises two vertical sideuprights 16 which are mortised to an upper horizontal brace it; and alower horizontal cross member 29. The upper horizontal brace 18 and thelower horizontal cross member are connected by a central verticalsupport 22 defining two openings 24 for the removable inserts E. Thelower horizontal cross member is slotted and capped with metal or woodplates 26 which contain holes 28 adapted to receive and provide aweather-tight seal for the cranks 12 Vertically swinging latching levers36 are pivoted at 32 to the central vertical support 22 at the interiorof frame D for releasably interlocking engagement with a companion catch34 mounted upon the interior face of the easement sash A and designed todraw sash A firmly against the window casing B from a point inside thestorm sash within the building.

The vertical side uprights 16 and the central support 22 are rabbetedadjacent to openings 24 and facing interiorly to define vertical rails36 with edges 36A for slidably supporting the removable inserts E. Theupper horizontal brace 18 is notched adjacent to openings 24 and facinginteriorly to form horizontally extending rabbets 38 whose verticalsides 38A lie .in the same plane as the vertical rails 36 but whosehorizontal edges 38B are indented to a greater extent than edges 36A.Sheet metal flanges 40 are fastened to the interior face of thehorizontal brace 18 adjacent to openings 24 and are curved slightly atits bottom portion in an inward direction to form deep, horizontallyextending slots 42 having lips 44.

The lower horizontal cross member 20 is rabbeted adjacent to openings 24and facing interiorly to form notches 46 whose vertically extendingshoulders 46A lie in the same plane as rails 36 but whose indentedbottom 46B extends slightly below the bottom portion of the opening 24.Horizontally extending inwardly curved lips 48 are mounted upon theinner face of the horizontal cross member 2t} adjacent to notches 46 todefine a shallow lipped recess 50.

The removable inserts E comprise four types: an upper storm window El, aventilator E2, a full screen insert E3, and a full glass storm windowinsert (not shown).

The upper storm Window insert E1 comprises a central glazed portion 52and a surrounding extruded metal frame 54. The metal frame 54 has aspecially designed bottom cross piece 56 with a downwardly projectingtongue 58 whose engaging surface 58A is flush with interior surface 56Aof cross piece 56 from which the tongue 53 extends. Horizontallyextending beyond the frame 54 and mounted upon its interior surface 56Aare a pair of latching ears 60 which are adapted to engage with a pairof vertically clasping lugs 62 screwed to the interior face of verticaluprights 16 and central support 22.

The ventilator E2 comprises a central glazed portion 64 and asurrounding extruded metal bezel 66. The bezel 66 has a pin 68 whichengages a chain 70 which, in turn, is mounted to the upright 16. Thechain 70 holds ventilator E2 in an inwardly open position when thebottom of the ventilator is hingedly located within the shallow lippedrecess 50.

To introduce the upper storm window insert E1, it is interiorly cantedfrom top to bottom and while its upper edge rests upon the verticalrails 36, the top of the insert is slid beyond the relieved lip 44 intothe deep slot 42 until stopped by horizontally extending edge 383.

While still pressed against the rails 36 and edge 38B, the upper insertE1 is swung in a vertical plane fiush against the rails 36 and thendropped until the horizontally extending latching ears 60 engage thevertical clasping lugs 62. The uppper portion of the insert E1 ismaintained against the rabbeted edge 38A by the inner face of flange 40.

To maintain the ventilator E2 in a closed position, the upper stormwindow insert E1 is slid up into the clearance of slot 42 and thehorizontally hinged ventilator is swung against rails 36. The upperinsert is then lowered until its lower edge rests upon the upper edge ofthe ventilator E2 while the downwardly projecting tongue 58 grasps theupper interior portion of ventilator E2 maintaining it flush against theside rails 36. The vertical clasping lugs 62 provide a wedge for thelatching ears 60and prevent rattling of the upper insert E1 and theventilator E2.

The full screen insert E3 is introduced into the frame D by incliningthe insert against rails 36 within the slot 42 and swinging the insertinto a vertical plane. The insert E3 is then lowered into a lockedposition within the lower shallow slot 50. The full glass storm windowinsert (not shown) is similar to the full screen insert E3 and ismounted in a similar manner.

Although my invention has been described in considerable detail, suchdescription is intended as being illustrative rather than limiting,since the invention may be variously embodied, and the scope of theinvention is to be determined as claimed.
